As far as I know, the game is endless. As for the game itself, I like the concept, but the bosses are a little too tough. I also wish there were more classes to choose from.
I think I may email the game creator to see if there is in fact a "final" level. One thing I noticed is that once you hit 100 on a skill, it starts over rather than being cumulative. I was equpped with a shield that didn't work because I supposedly didn't have enough points, had to re-equip a different one. Also, the game does get pretty repetitive after playing for awhile. The way I'm equipped now, I'm dealing 15,000 - 25,000 damage per hit, 2 or 3 hits on the normal ones does them in. Decent game, but if it's "endless", I've about had enough of it.
I did email the game creator and got no response. Strange, since most creators are happy to hear about problems or to answer gameplay questions. Specifically, I asked him why on a current screen I get a "0" hit point count when hitting one of baddies. I also asked if the game does have a conclusion or a "final" battle. No answer from him - I guess I'm done with this one.
